Who shall prevail, Lu Banchi's Ming and Qing editions or Sui and Tang editions?
Lu Banchi's Ming and Qing editions are more accurate than Sui and Tang editions. After all, Lubanchi in the Ming and Qing Dynasties had reached a high level.
Lu Banchi, the full name of "Luban Building Ruler", also known as "Lu Banchi", is a measuring tool used in building houses and is also a square ruler used by craftsmen today. It is mainly used to check whether the planed plates, purlins and structures are vertical and whether the edges and corners are at right angles.
Second, is the geomantic Lu Banchi on the market accurate?
Lu Banchi, which is popular in the market now, is not accurate. This kind of Lu Banchi was first produced by a company in Shanghai. Later, various manufacturers followed suit, and the format of steel tape measure was wrong. It uses a 42.9 cm Lu Banchi, which is inaccurate, and a 50.4 cm Lu Banchi, which is inaccurate. So what's the standard size of Lu Banchi?
The real half-foot, 1 half-foot is equal to 35 cm. 1 ruler is equal to 33.333...cm, while half a foot 1 ruler is equal to 1 ruler +5 points. The standard size of Lu Banchi is 46 cm, and the allowable deviation is 0.5 cm. There is a Lu Banchi in the Palace Museum in Beijing, which is 46 cm long, 5.5 cm wide and 1.35 cm thick, which can be verified.
Third, the use of Lu Banchi
Lu Banchi is divided into two layers, the upper layer is called the door ruler, and the lower layer is called the Ding Lan ruler. Household meters are used to build houses and measure residential houses and electrical appliances. There are eight words on it: wealth, illness, separation, righteousness, official, robbery, harm and capital. Under each word, it is divided into four small words to distinguish the meaning of good and bad.
1, financial word gate, used for ordinary families.
2, the word door, used for medical and pharmacy business.
3, away from the word gate, used for some mobile services.
Ziyimen is used in schools and some private families.
5, the official word door, used for official affairs.
6, rob the word door, mostly used for animal pens, but also for prison.
7. One-word gate is the same as one-word gate.
8. This door is used for shops.
High choice of words: only choose the words "wealth" and "righteousness"; These dimensions of "wealth" and "righteousness" can also be used in width, and the other six dimensions can only be used in width, not in height. That is to say, when choosing the size of the eight-character gate, the size of the two-character gate of "wealth" and "righteousness" is the best.
